A kind of opening and closing signal output assembly

Abstract

This invention discloses a circuit breaker opening / closing signal output component, including a housing. The housing houses a signal processing module and a microswitch electrically connected to the signal processing module. The housing also has a pivot pin, on which a swing arm is mounted. One end of the swing arm is linked to the contact system inside the circuit breaker. When one end of the swing arm is subjected to force, the other end triggers the microswitch, changing the state of its normally open or normally closed contact and outputting an opening / closing signal. By utilizing the linkage between the swing arm and the contact system, with one end of the swing arm close to a rotating shaft within the contact system, rotation of the shaft causes the swing arm to rotate on the pivot pin, triggering the microswitch at the other end. The change in the normally open or normally closed contact state of the microswitch then outputs an opening / closing signal. Based on this, the opening / closing status information of the circuit breaker can be reliably output, reducing the risk of false alarms and missed alarms.

Technical Field

[0001] This invention relates to the field of circuit breaker technology, specifically to a circuit breaker opening and closing signal output component. Background Technology

[0002] Circuit breakers require status feedback during operation to determine if the action was executed correctly. Traditionally, circuit breaker control and status feedback are achieved through wire connections, requiring manual connection and control by the user. This method presents several problems. First, the need for numerous wires makes assembly cumbersome, increasing production costs and time. Second, manual wire connections are prone to errors or poor contact, leading to malfunctions or inaccurate status feedback. Most importantly, traditional methods struggle to achieve automated control and intelligent feedback for circuit breakers, limiting their application scope and efficiency. Summary of the Invention

[0017] The embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. In the description of the present invention, it should be understood that the terms "upper," "lower," "front," "upper surface," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the present invention.

[0018] Please see Figure 1-9 The present invention provides an embodiment of a circuit breaker opening and closing signal output component, comprising a housing 3, a signal processing module 31 and a micro switch 36 electrically connected to the signal processing module 31 on the housing 3; the housing 3 also comprises a pivot pin 310, on which a swing arm 35 is mounted, and one end of the swing arm 35 is linked to the contact system 2 inside the circuit breaker; when one end of the swing arm 35 is subjected to force, the other end of the swing arm 35 triggers the micro switch 36, and the state of the normally open or normally closed contact of the micro switch 36 changes, thereby outputting an opening and closing signal.

[0019] Specifically, when the housing 3 is inserted into the slot 5 in the middle plate 4, one end of the swing arm 35 passes through the slot 5 and approaches the contact system 2 provided on the base 1. When the shaft of the contact system 2 rotates, it can cause the swing arm 35 to rotate along the shaft pin 310. The other end of the swing arm 35 away from the contact system 2 triggers the micro switch 36. Since the normally open or normally closed contact state of the micro switch 36 changes after it is triggered, the signal processing module 31 uses the micro switch 36 to output the change of the contact system 2 to the outside.

[0020] Based on this, a swing arm 35, a micro switch 36, a signal processing module 31, a power supply assembly 32, etc. are integrated on the housing 3, so that the output component can be installed on the molded case circuit breaker without affecting the performance and operating space of the circuit breaker itself.

[0021] Furthermore, since there are two microswitches 36 and two swing arms 35, and the two microswitches 36 and the two swing arms 35 are symmetrically arranged on both sides of the housing 3, two dual microswitches 36 can be installed on the housing 3. When one microswitch 36 fails, the other microswitch 36 can still work normally, which greatly improves the reliability of the opening and closing signal output and reduces the risk of false alarms and missed alarms. At the same time, since a torsion spring 34 is also provided on the shaft pin 310, the swing arm 35 is reset through the torsion spring 34.

[0022] Specifically, the swing arm 35 is rotatably connected to the shaft pin 310 through the provided shaft pin hole 319, and the end of the swing arm 35 away from the contact system is also provided with a trigger plate 320, which contacts the contact of the micro switch 36 through the trigger plate 320; the middle part of the torsion spring 34 is sleeved on the shaft pin 310, one end of the torsion spring 34 abuts against the bottom surface of the trigger plate 320, and the other end of the torsion spring 34 abuts against the housing 3.

[0023] In summary, when the contact system 2 is reset, the torsion spring 34 causes the swing arm 35 to reset, so that the swing arm 35 can be reliably triggered when the contact system 2 is working again.

[0024] In addition, since there are two support rods 39 on both sides of the housing 3, after the mounting hole on the side of the micro switch 36 is connected to the support rod 39, the micro switch 36 can be reliably fixed on the housing 3 by the support rod 39, which can completely prevent the micro switch 36 from swinging when the swing arm 35 rotates.

[0025] To address the issue of uninterrupted power supply to the signal processing module 31 in the event of an external power outage, which could lead to timing errors in the information, a power supply assembly 32 is also provided within the housing 3, which supplies power to the signal processing module 31.

[0026] Specifically, the power supply assembly 32 includes a battery housing 311 for mounting the battery 315 and a battery cover 318 covering the battery housing 311; wherein the battery housing 311 is provided with a first pin 312 and the battery cover 318 is provided with a second pin 317. Therefore, the power supply of the battery 315 can be transmitted to the signal processing module 31 through the two pins. The signal processing module 31 can directly use existing technology, and its main function is to have a signal processing circuit, which can perform preprocessing such as filtering and amplification on the signal output by the micro switch 36, and then output the preprocessed information.

[0027] To prevent the power supply assembly 32 from separating during insertion and removal, the battery cover 318 is connected to the buckle 314 on the battery housing 311 by means of a buckle 316.

[0028] Because the housing 3 also has a mounting cavity 38, and a groove 37 is provided on the circumferential surface of the mounting cavity 38; wherein, after the battery case 311 is inserted into the mounting cavity 38, the protrusion 313 provided on the outer wall of the battery case 311 is adapted to and connected with the groove 37. Therefore, after the power supply assembly 32 is connected to the housing 3, the power supply assembly 32 can be stably and reliably located in the mounting cavity 38.

[0029] Meanwhile, the housing 3 is also provided with a connecting buckle 33, and the connecting buckle 33 is connected to the connecting hole 6 provided on the middle plate 4, so that the output component can be plugged in and unplugged as a whole, which is convenient for installation, maintenance and replacement.

[0030] Closing process: When the circuit breaker performs the closing operation, the circuit breaker body shaft rotates clockwise, squeezing one end of the swing arm 35 to make it rotate synchronously, thereby causing the other end of the swing arm 35 to disengage from the micro switch 36. At this time, the micro switch 36 generates a closing signal. After the signal processing module 31 detects the signal change, it processes it and sends it to the background monitoring system.

[0031] Tripping process: When the circuit breaker performs a tripping operation, the shaft rotates counterclockwise, releasing the pressure on the swing arm 35. The torsion spring 34 drives the swing arm 35 to reset, thereby pressing the micro switch 36 to generate a tripping signal. After being processed by the signal processing module 31, the signal is uploaded, thereby realizing accurate monitoring of the circuit breaker's tripping and closing status.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and these variations still fall within the protection scope of the present invention.
